We brought down a few bags of clear beads, underwater battery operated lights, a few fake orchids from michaels and floating candles. Cost was about $10 per centerpiece. Then we rented the vases and the mirror from the resort for $5 a piece. Instead of table numbers we did Boston / Philly Sports teams. They provided the table number holders at no extra cost.

Here is mine with flowers. My husband was actually the one that had a preference - I thought they both looked nice! The nice thing is though - you can reuse the flowers (we put one on the head table and one on the cake table) so it saves you some money there (or at least helps alleviate the extra cost). We also kept the flowers in our room for the last few days - then passed them on to a guest that was staying later, so they got some use

One thing I just noticed - looking through photos, from the side/back and inside it looks almost like a plain one, to give some perspective.
